[font=文泉驿正黑][size=2][font=arial, verdana, tahoma, sans-serif][size=2]Hi all,

[/size][/font]
    In FirefoxOS, there is a Cubevid application. It use vp8 software codec and the performance is not well.

    We use DS5 to find the hot spot, YUV convert to RGB32. You can see [size=2]FastConvertYUVToRGB32Row_C@[/size][size=2]yuv_row_c[/size][size=2].cpp[/size][size=2] in attachment[/size] .

    Can you help me to use GPU(Mali300) to convert YUV to RGB?

    Thanks for your help!

    You can get FFOS code as below.

    git clone git://github.com/mozilla/releases-mozilla-central

Hi James,

This post has some sample shader code for this purpose. You would need to push the YUV data as a texture to the GPU.

Let me know if this helps or if you need any more guidance.

Thanks,
Chris
